Abstract

Small-scale fishers on Caribbean coral reefs have exploited fish spawning aggregations (FSAs) for generations, but intense fishing has led to the loss of traditional aggregation sites. In many areas, the traditional ecological knowledge (TEK) of fishers has contributed greatly to the characterization of spawning aggregations and implementation of local conservation initiatives. TEK has identified more than 40 potential FSA sites along the coast of the Mexican Mesoamerican Reef. These sites have been characterised and scientifically validated, in some cases with traditional western science and in others, with a participatory citizen-science approach. The objective of this work is to compare the science and conservation outcomes at these FSA sites. We report that those FSA sites where scientific surveys were conducted without community participation remain unprotected. By contrast, the FSAs where local fishers were engaged in characterization and subsequent monitoring are now protected at the behest of the fishers themselves. Conservation initiatives to protect FSAs can be more effective through a combination of TEK, western science, and participatory citizen science involving local fishers.

Worldwide, conventional fisheries management has relied on traditional tools such as size and catch limits, gear restrictions, and closed seasons. In many developing countries, however, such tools are difficult to implement given limited resources for effective enforcement. Small, completely protected marine reserves have been cited as effective tools for protecting FSA sites (Erisman et al. 2015). However, knowledge gaps exist in the understanding of the location of FSAs (Kobara et al. 2013) and, as such, managers can be reluctant to implement conservation measures. A review of the objectives for 55 Caribbean multiuse protected areas found that only four considered FSA management in their design (Appeldoorn and Lindeman 2003). In one extreme example, a Black Grouper FSA was discovered just beyond the boundary of a protected area (Eklund et al. 2000) and therefore offered no protection.

In his thoughtful and somewhat provocative paper “The case for data-less management,” Johannes (1998) explained how conventional biological training has created conditions in which scientists can be reluctant to commit to conservation management decisions without a quantitative description of the resources at hand. However, due to the data gaps still present in FSA science, and the continued population declines in many fish species that aggregate to spawn (Sala et al. 2001, Sadovy and Domeier 2005, Sadovy de Mitcheson et al. 2012), data-poor management approaches are now being considered. Data-poor management, however, does not necessarily mean data-free (as proposed by Johannes 1998), and advocates of the approach draw on all available data to propose optimal management solutions that account for both the existing scientific information and the TEK of the local fishers (Heyman 2011).

In this study, we define traditional western science (WS) as research conducted by trained scientists (from academia or NGOs) that is objective, generally quantitative, analytical, and reductionist, and often results in publications and, in some cases, policy and management recommendations. In contrast, participatory citizen science (CS) uses a western science approach but, in addition, involves the continued participation of fishers in the scientific aspects of research, analysis, and in making and implementing policy recommendations.

Both traditional western science and participatory citizen science approaches have been used to verify and characterize FSA sites along the Mexican portion of the Mesoamerican Reef (MAR), but no comparisons between these techniques and their respective conservation outcomes have been previously made. All potential FSA sites were originally identified via TEK. Of these, some were characterized using solely traditional western science and conducted by scientists from either academia or from NGOs. Others were characterized using a participatory citizen science approach involving local fishers supported by researchers and NGOs. The objective of this paper is to compare the scientific and conservation outcomes achieved by these differing approaches.

Methods

Study Area

The MAR extends over 1,000 km from the tip of the Yucatan Peninsula in Mexico to the Bay Islands of Honduras. The study area covers a 230 km section from the northern edge of the Sian Ka’an Biosphere Reserve to Xcalak on the Belize border (Figure 1). This central and southern section of the Mexican State of Quintana Roo lacks the mass tourism destinations found in the north of the peninsula and is home to three Protected Areas (PAs): The Sian Ka’an Biosphere Reserve complex (SKBR), Banco Chinchorro Biosphere Reserve (BCBR), and Xcalak Reef National Park (XRNP). All PAs are zoned as multiuse; fishing is permitted in most of the area but with restrictions, particularly on gear type.

Map of the study area.

Fishing activities occur throughout the study area, with seven fishing cooperatives totalling approximately 209 fishers principally catching lobster and small amounts of finfish. An eighth cooperative (eight fishers) exclusively targets finfish. Approximately 15 additional individual permit holders and an unknown number of unregulated fishers operate in the area.

Review of FSA Scientific Knowledge in the Mexican MAR

TEK provides the foundation for all FSA work in the Mexican MAR. The first study to document several FSAs was completed by Aguilar-Perera (1994), while Sosa-Cordero et al. (2002) published the most comprehensive study to date. In both cases, the principal data source was interviews and surveys with veteran fishers, completed by documented sources and grey literature. Sosa-Cordero et al. (2002) identified 39 potential FSA sites for diverse species. Local NGOs replicated the studies on a smaller scale during the mid-2000s (Franquesa-Rinos and Loreto-Viruel 2006, ASK and COBI 2010). The NGOs worked closely with the fishers to reconfirm and prioritise the Sosa-Cordero et al. (2002) data. The 39 original FSAs were revised down to 29, as some sites were clustered and likely represented the same FSA (Fulton et al. 2016).

We searched published literature available in online scientific databases and in grey literature to find references to fieldwork conducted in the region. Three groups were identified: Academics using western science without fisher involvement (western science “WS”), NGOs using western science without local fishers (“WS*”), and mixed groups of academics, NGOs, and local fishers (citizen science “CS”). For each study, we identified the methodology used, if bathymetric maps were created, if FSAs were validated and by what method, and the level of involvement of local fishers.

CS: Citizen Science (participatory science involving local fishers, NGOs, and academics). WS: Academics using western science without fisher involvement. WS*: NGO using western science without local fishers.

The San Juan FSA (Figure 2; Table 1), in the northern part of the SKBR, was characterized by a local NGO and trained fishers from the community in 2005 (Franquesa-Rinos and Loreto-Viruel 2006) and 2008 (ASK and COBI 2010). The site was mapped and biologically characterized through underwater visual census (UVC). Divers reported purported spawning aggregations of 200 Nassau Grouper and 100 Black Grouper (Mycteroperca bonaci), from changes in colouration and behaviour, located on the shelf-edge in 35 m of water. Fishers from the same community returned in 2015 with other scientists and reported 50 Nassau Grouper and 30 Black Grouper (Fulton et al. 2016). Due to the observed decline in fish abundance in these aggregations, recommendations were made to the community to close the site to fishing.

The Punta Allen FSA, also in northern SKBR, followed a similar process to San Juan. NGO and community characterizations in 2005, 2008, and 2015 (Franquesa-Rinos and Loreto-Viruel 2006, ASK and COBI 2010, Fulton et al. 2016) reported 1,000 Nassau Grouper located at 35 m depth on a large spur and groove coral reef. The fishers reported that the site has rarely been fished in the last 10 years, but with the observed abundance of this endangered species in a spawning aggregation, it was considered worthy of legal protection.

The Punta Herrero site, located in the southern part of the SKBR, was characterized through CS with fishers from the cooperative “José María Azcorra” beginning in 2008. A small FSA of Nassau Grouper was reported at a depth of 30 m, on a small drop-off in an area of strong currents (ASK and COBI 2010). Site protection was proposed in 2010 to protect the Nassau Grouper FSA. Between 2013 and 2015, fishers and scientists mapped and further characterized the site with UVC and reported FSAs of 150 Nassau Grouper, 30 Yellowfin Grouper (Mycteroperca venenosa), 1,500 Mutton Snapper (Lutjanus analis), and 800 Dog Snapper (Lutjanus jocu) (Fulton et al. 2016).

Characterization of FSA sites using western science (WS/WS*)

Fishers had been aware of a Nassau Grouper FSA at Mahahual for over 100 years (Aguilar-Perera 1994) (Figure 2). The site was initially described and mapped between 1988 and 1990 by WS (Aguilar-Perera 1994), and UVC were used to document 1,000 Nassau Grouper on a shallow reef between 10 and 16 m depth. Aguilar-Perera (1994, 2013) was the first to make management recommendations for FSA sites in the Mexican MAR, with the particular aim of preventing the disappearance of the Nassau Grouper FSA in Mahahual. These recommendations included banning spearguns, implementing a closed season, and improving surveillance and enforcement. The study also recommended working with fishers to highlight the ecological importance of the FSA in Mahahual and providing economic alternatives to reduce fishing pressure on the aggregation.

The Maya-Ha Black Grouper FSA site, located in the Costa Maya region, was originally verified by a local NGO in 2009 without local fisher participation (ASK and COBI 2010) (Figure 2; Table 1). Site-specific management recommendations were not made. The site was revisited in 2016 with fishers who were not local to the area. The team produced a bathymetric map of the site and used UVC to document aggregations of 30 Black Grouper and 45 Cubera Snapper (Fulton et al. 2016).

In Xcalak, commercial catch of Nassau Grouper was registered and UVC conducted by WS on the FSA between 2001 and 2002 (Medina-Quej et al. 2004). The FSA of 3,000 groupers, the largest reported in the literature in Mexico, forms on a spur and groove reef at approximately 35 m depth (Figure 2; Table 1). The researchers reported that fishing pressure was low, and recommended that the management plan for the PA take the FSA site into consideration.

Researchers (WS) published the first record of a Mutton Snapper FSA in Banco Chinchorro (Castro-Pérez et al. 2011). Coordinates were provided for the FSA based on catch data provided by the fishers, however, the FSA was not visually verified. The authors mentioned that fishing impact in Banco Chinchorro is low to moderate due to the restrictions of the biosphere reserve, and recommended seasonal closures for the FSA. A community CS monitoring team was established in 2012 in collaboration with NGOs and the reserve authorities. The team visually confirmed an aggregation of 3,000 Mutton Snapper at a location 3 km from the shallow banks where the aggregation was first reported, at a depth of over 40 m on the shelf edge (Figure 2; Table 1; Heyman et al. 2014).

Protection Status

Mexican legislation includes several instruments that can be used to protect critical habitat, ecosystems, or species. The two instruments relevant for this article and implemented in the Mexican MAR are multiple-use protected areas managed by the National Commission of Natural Protected Areas (CONANP in Spanish) and no-take zone (NTZ) Fish Refuges managed by the National Commission of Aquaculture and Fisheries (CONAPESCA). PAs include different zoning schemes that can limit and prohibit fishing, such as core zones. Fish Refuges are a relatively new instrument, created under the Sustainable Fisheries and Aquaculture Law in 2007 (Secretaria de Gobernación 2007) and first implemented in 2012.

The three northernmost FSA sites (San Juan, Punta Allen, and Punta Herrero) are located in the SKBR. This Federal PA was established in 1986 (Secretaria de Gobernación 1986) and contains a multiple-use zoning scheme of which 100 km2 are closed to fishing, except for subsistence and lobster fishing. The management plan for the PA states that grouper and snapper FSA are found inside the PA no-take zones (Secretaría de Medio Ambiente y Recursos Naturales 2014), however, the three confirmed FSA were verified 20 years after the PA was created, and efforts to locate FSA in the PA no-take zones have not been successful. The characterized San Juan FSA described in the study is located 2.8 km from one such no-take zone, the Punta Allen FSA 6 km distant, and the Punta Herrero FSA 4.4 km away (Figure 2). Effort control also exists, as spearguns and nets are prohibited throughout the PA.

In 2013, the Punta Herrero FSA was protected under the fisheries legislation at the petition of the local fishers with help from local NGOs (Secretaria de Gobernación 2013). The Punta Herrero Fish Refuge covers 4.3 km2 and represents the first time that this legislation was used to protect a FSA in Mexico. In 2016, the San Juan and Punta Allen sites were also protected at the petition of the fishing community using the same legislation (Secretaria de Gobernación 2016), with a 16.3 km2 and 15.8 km2 Fish Refuge respectively.

Protection of FSA sites characterized using western science (WS/WS*)

The Mahahual and Maya-Ha FSAs are not found within a PA. The Mahahual FSA was reported as extinct by 1996 (Aguilar-Perera 2006, 2013). Considerable WS research was conducted on the site (Aguilar-Perera 1994, 2006, 2013, Aguilar-Perera and Aguilar-Davila 1996), and it remains the best-described FSA to date in Mexico despite no continuous monitoring program being implemented. Management recommendations were implemented as the size of the FSA diminished, with CONAPESCA enacting a ban on spearguns and gill nets in 2006 and a complete ban on fishing during spawning season in 2007 (Aguilar-Perera 2013). Lack of enforcement saw these actions abandoned the following year. The Maya-Ha FSA is believed to be fished from fishers from the town of Mahahual, but no data exist on effort or landings, and no efforts have been made to manage or protect the FSA.

In Xcalak, the FSA is located within the XRNP, a PA created in 2000 (CONANP 2004). The PA contains a specific “Special Production Zone – Grouper” (Zona de Aprovechamiento Especial Mero), in which the management plan recognises the presence of a FSA (although commercial fishing is permitted). This site, known as Punta Gavilan, was identified from TEK over 20 years ago (Aguilar-Perera 1994), but no data have since been published to confirm the presence of spawning fish. The visually verified aggregation (Medina-Quej et al. 2004) lies 1.9 km to the south of the Special Production Zone. The site continues to be monitored by a local research institute (WS).

The Banco Chinchorro FSA is found within the BCBR, a Federal PA that includes 68 km2 of no-take zones. Effort controls also exist; spearguns are prohibited by the management plan during fish reproduction seasons (SEMARNAP 2000). Catch data is collected during the spawning season by the reserve authorities. The recently documented Mutton Snapper FSA is located approximately 800 m beyond the edge of the nearest NTZ (Table 1, Figure 2).

Discussion

Conservation Outcomes of WS, WS*, and CS-led FSA Studies

This study compared the outcomes from case studies using western science (WS) to those using a participatory citizen science (CS) approach for the characterization and conservation of fish spawning aggregation sites in the Mexican MAR. All potential spawning sites were first identified with fishers’ traditional ecological knowledge. Our results show that the four FSA sites characterized by researchers using WS without community involvement (Mahahual, Maya Ha, Xcalak, and Banco Chinchorro) remain open to fishing. In each of these cases, WS provided site characterizations and clear management recommendations (Aguilar-Perera 1994, Medina-Quej et al. 2004, ASK and COBI 2010, Castro-Pérez et al. 2011). None of the recommendations have been implemented effectively, however. One site serves as an extreme example: The FSA site at Mahahual was fished to extinction (Aguilar-Perera 2013). By contrast, the three sites where the fishing community took part in the FSA characterization, monitoring, and evaluation (San Juan, Punta Allen, Punta Herrero) are now protected within no-take zones after fishers petitioned the government for their establishment (Secretaria de Gobernación 2013, 2016; Table 1).

The successful implementation of fisheries conservation measures presented in this paper occurred when western science, citizen science, and traditional ecological knowledge were effectively combined. The protection of three FSAs documented herein was made possible through community level collaborations between researchers, civil society, government, and fishers. This citizen science programme resulted in the training of 38 local fishers as SCUBA divers, who characterized the FSA sites near their communities and generated the data required for their protection using the existing legal framework. The sites were protected by the National Commission of Aquaculture and Fisheries (CONAPESCA) under the fisheries legislation, a flexible and dynamic management tool. These areas were, and continue to be, considered both data-poor and with low levels of enforcement, although fishers operate community surveillance programmes with some governmental support.

In contrast, at the four FSAs where a CS component was not included (Table 1), information and management recommendations were made (Aguilar-Perera 1994, 2006, Medina-Quej et al. 2004, Castro-Pérez et al. 2011), but the recommendations were not implemented with long-term success. For example, CONAPESCA temporarily implemented some of the recommendations made for the Mahahual FSA, however, the regulations were enforced only briefly, and fish stopped aggregating at the site shortly after (Aguilar-Perera 2006, 2013). Incidentally, this FSA had been fished at low levels for decades, but a race to fish in recent years, driven by a growing population and tourism developments, and including the use of new fishing gear, harpoons and, reportedly, dynamite (Aguilar-Perera 1994) quickly led to its extinction.

Driving factors for FSA protection

Social and economic factors need to be recognised as important contributions to the enabling environment for the establishment of the three NTZs in this study. The cooperatives that created the NTZs form part of the Kanan Kay Alliance (www.alianzakanankay.org), a voluntary, multisectoral collaborative network formed by more than 40 organisations including fishing cooperatives, government agencies, NGOs, research centres, and philanthropic foundations with the aim of creating NTZs and encouraging sustainable fishing practices. The Alliance creates dialogue spaces in which conservation initiatives are coordinated. Fishers are active participants and thus feel included and more willing to implement the recommendations (Moreno et al. 2016). Before the NTZs were implemented, surveys were conducted to evaluate the perception of fishers towards fisheries, NTZs, and the community-based process (Velez et al. 2014). Additionally, socioeconomic studies were conducted on the fishing cooperatives (Bobadilla 2014) with the results allowing focussed capacity-building for each cooperative’s needs, including strengthening their internal structure and leadership to allow them to invest in conservation and sustainable fishing.

It is also possible that the lucrative lobster fishery in the SKBR has reduced pressure on the finfish fishery in the past decades, making FSA protection more amenable within the traditional fishing grounds. However, the extent to which fishers are willing to protect FSAs varies in each community. The cooperative in Punta Allen now lands very few fish (10-year average of 3.7 tonnes per year), and closing a FSA site to fishing likely had little effect on production. However, the cooperative in Punta Herrero continues to exploit the finfish fishery (10-year average of 49.5 tonnes per year) to complement their income from lobster, and the creation of the marine reserves has required a stronger commitment by the community. At the same time, regional stocks of transient spawning fish such as groupers continue to decline (Secretaria de Gobernación 2014).

In contrast, Mahahual is the only coastal community in the Mexican MAR without a registered fishing cooperative based in the village, reducing the possibility of collaborative work with the fishing community. Mahahual residents also have a pessimistic view of the future; 68% of residents expect fewer fish in the future and only 12% believe that regulations can change the situation (Cinner and Pollnac 2004). The fact that several conservation initiatives have failed to be successfully implemented in Mahahual (e.g., Amigos de Sian Ka’an 2003) reflects that the scope and target of such projects did not successfully address underlying conditions, unite the community, nor seek to strengthen socioeconomic factors that could promote successful achievement of conservation goals (Cinner and Pollnac 2004).

Promoting an enabling environment for FSA site protection

Heavy fishing pressure on aggregations is not sustainable (Sadovy and Domier 2005). In all cases, a precautionary approach is recommended (Erisman et al. 2015, Sadovy de Mitcheson 2016). WS is often the first to raise conservation concerns and to make management recommendations; however, this raises the question of who is responsible for implementing the conservation measures. Should researchers always make management recommendations? And how can we improve the implementation of such recommendations? The “knowing-doing gap” that has been identified in conservation science (Knight et al. 2008) is relevant to this discussion. Whilst research faculty tenure and promotion at most academic institutions are generally dependent on excellence in research, teaching, and service, implementation of research recommendations, including conservation, is generally not linked with job security and advancement. Though some institutions are increasingly valuing service learning and societal contributions in the tenure and promotion process (June 2013), there have traditionally been disincentives within academia for cross-disciplinary research and its applications in conservation (Arlettaz et al. 2010, Gibbons et al. 2008; Knight et al. 2008). This is definitely the case in Mexico, where the National Council of Science and Technology (CONACYT) can make substantial contributions to top researchers’ incomes based on research productivity, defined in terms of publications and grants (Altbach 2015). Critics of the reward system also argue that it discourages collaboration and more heavily rewards papers published in English (Altbach 2015). These incentives contribute to the implementation gap, as the most important research may not be immediately available to local practitioners, or in a language they understand, and academics are not rewarded by their employers for participating in the implementation of their recommendations.

However, the burden of implementing management recommendations must fall on all sectors. Collaborative efforts between researchers (who provide the technical expertise) and NGOs (who often provide long-term financial support and continuous presence in fishing communities, particularly in developing countries) are becoming commonplace (Da Fonseca 2003, Hamilton et al. 2011). In Mexico, monetary (Pérez-Cervantes et al. 2017) and political constraints (Hernandez and Kempton 2003) often limit government capacity to incorporate recommendations into adaptive management schemes. Delayed action can be costly (Mangin et al. 2018), and all sectors should work alongside the fishing communities to incorporate TEK, find socially acceptable solutions, and promote community buy-in.

This study also revealed the need for TEK to be accompanied by effective science to guide conservation and management (Hamilton et al. 2012). In those sites in which federal protected area zoning (e.g., SKBR, BCBR, XRNP) occurred before adequate science had been completed (either WS or CS), FSA sites that were described by TEK alone were not successfully protected. FSAs were subsequently found close to, but not in, NTZs (Table 1). Field verification of FSAs has shown that TEK is not always accurate, and anecdotal information needs to be validated through field observations. In the Mexican MAR, it appears that TEK data were collected before the PAs were zoned, but field verifications were not completed to adequately geolocate the FSAs. For example, the management plan for the SKBR (Secretaría de Medio Ambiente y Recursos Naturales 2014) recognises the importance of protecting FSA sites and states that the zoning protects FSAs of grouper and snapper. Unfortunately, despite considerable effort by the CS teams, to date it has not been possible to visually verify these sites, and the only confirmed sites are located just outside the NTZs. The management plan acknowledges that information is lacking regarding FSAs and that further studies are required to locate the sites with precision, however, rezoning federal protected areas can be a long process. The flexibility offered by the Fish Refuge legal framework allows for bottom-up approaches whereby fishers can directly petition the federal fishing authorities to enact conservation measures. The law was first used in 2012, and fishers feel a great sense of ownership for the NTZs that they proposed and that were ultimately created. Compromises, however, must also be made. The three NTZs have each been established for a minimum period of five years, with options for renewal, modification, or removal at the end of the period. This time is too short for recovery of grouper biomass to pre-exploitation levels, with marine reserve design principals recommending permanent reserves (Green et al. 2014) to maximise benefits. However, this was the first time this type of protection was applied to FSA in Mexico, and fishers must become familiar with the framework.

Though worldwide FSA protection within NTZs is woefully inadequate (Russell et al. 2014), there are a growing number of successful examples where FSAs have been placed within NTZs with varying methods and levels of local support. For example, a Florida fisher suggested Riley’s Hump in the Florida Keys for NTZ status because it served as a multi-species FSA (Locascio and Burton 2016). Characterization was conducted largely by scientists, and the initial local reaction to the closure was hostile. Local residents showed growing support after seeing that the protection has effectively fostered fish returning to spawn (DeMaria pers. comm., Burton et al. 2005). FSA conservation projects in the Solomon Islands also have illustrated the value of combining TEK with citizen science (Hamilton et al. 2012). The community reported declining catches, but researchers and NGOs stepped in to raise awareness and involve the community in monitoring their resources. This led to the creation of a community-based NTZ at the site. In Belize, eleven multi-species FSA sites were closed in 2003 with full support from fishers, following three years of extensive characterization work conducted in partnership between researchers, national and international NGOs, the Government of Belize, and fishers as citizen scientists (Heyman 2011).

By contrast, many examples exist where FSA conservation efforts have been hampered by insufficient community involvement in research. In the Cayman Islands, scientific characterization efforts from the national government’s Department of Environment, with support from the international NGO REEF, led to the protection of an important Nassau Grouper FSA, which has since shown impressive recovery (Heppell et al. 2012). However, the scientific efforts for characterization and monitoring did not include most local fishers, thus the fishing community has perceived the closure negatively. Similarly, an important FSA site for groupers and snappers in Alacranes Reef, Mexico (Aguilar-Perera et al. 2008) was proposed as a 513 km2 NTZ in 2014. However, this initiative was not conducted in collaboration with local fishers or academics, causing the Regional Federation of Fishing Cooperatives in Yucatan to react with surprise and concern to the lack of consultation, and pressure from the fishing industry has since derailed the proposal.

In conclusion, this study illustrates that involving small-scale fishers as citizen scientists can play an important role in creating an enabling environment whereby fishers support full protection of FSAs in the Mexican MAR. We concur with McKinley et al. (2015) that citizen science contributes to natural resource science, management, environmental protection, and policymaking. In addition, whilst other factors are important (including underlying socio-economic conditions and awareness-raising efforts), the three-pronged approach of traditional ecological knowledge, western science, and participatory citizen science is vital for effective conservation outcomes.
